我需要做什么才能使我从 GeoGebra 获得的图形位于论文的中心？
答案1
GeoGebra 提供的输出总是包含一个\clip大多数时候都是错误的指令。
\clip以下是注释掉该行后的输出：
\begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=1.0cm,y=1.0cm, scale=1]%line cap=round,line join=round,>=triangle 45,x=1.0cm,y=1.0cm, scale=1
%\clip(-4,-1.6) rectangle (5.5,1.6);

\draw [line width=0.35mm] (0.,0.)-- (1.,1.);

\draw [line width=0.35mm] (2.,0.)-- (4.,0.);
\draw [line width=0.35mm] (3.,1.)-- (4.,0.);
\draw [line width=0.35mm, loosely dotted] (3.,-1.)-- (4.,0.);
\begin{scriptsize}
\draw [fill=black] (0.,0.) circle (2pt) node[yshift=0.4cm] {\large A};
\draw[fill=black] (1,1) circle (2pt) node[yshift=0.4cm] {\large B};
\draw[fill=black] (1,-1) circle (2pt) node[yshift=-0.4cm] {\large C};

\draw[fill=black] (3,1) circle (2pt) node[yshift=0.4cm] {\large G};
\end{scriptsize}
\end{tikzpicture}
以下是删除%之前内容后得到的结果：\clip
无论如何，代码都应该完善。例如，scriptsize环境很有趣。我还会删除\large命令并简化一些构造。
